Toy building element with a spring mechanism

Abstract

A toy building set element is formed of a first part and a second part which is slidable and resiliently journaled with respect to the first part. Both of the parts have coupling elements thereon which permit coupling of the parts to other elements of the toy building set. One of the parts may be adapted to receive a shaft through a cylindrical opening that runs perpendicular to the displacement direction of the parts with respect to each other.

We claim: 
     
       1. A toy building set comprising: toy building blocks, each block having a first face with at least one protruding stud and a second face opposite to said first face provided with at least one recess dimensioned to receive a protruding stud from another block in a frictional engagement;   at least one of said blocks being formed of a first part having said first face and a second part having said second face, said second part being resiliently and slidably connected to said first part for movement of said first and second faces of said at least one block toward and away from one another; and   one of said first and second parts having means for mounting a wheel.   
     
     
       2. The toy building set in accordance with claim 1 wherein said wheel mounting means includes a wheel axle receiving through hole extending though said one of the parts. 
     
     
       3. The toy building set in accordance with claim 1 wherein said wheel mounting means includes a wheel receiving stud protruding from a surface of one of the parts. 
     
     
       4. The toy building set in accordance with claim 2 wherein said through hole extends in a direction generally perpendicular to the direction of movement of said first part with respect to said second part. 
     
     
       5. The toy building set in accordance with claim 15 wherein said stud extends in a direction generally perpendicular to the direction of movement of said first part with respect to said second part. 
     
     
       6. A toy building set comprising: toy building blocks, each block having a first face with at least one protruding stud and a second face opposite to said first face provided with at least one recess dimensioned to receive a protruding stud from another block in a frictional engagement;   at least one block having a first part having one said first face and a second part having one said second face, said second part being resiliently and slidably connected to said first part for movement of said first and second faces of said at least one block toward and away from one another.
